Last night I lost all my HD stations, Espnhd, and such. This a.m. I check Sat signals and could see all 5 Sats. Last night I could not. I ran setup and everything is OK except 99b, which fails. I can see a signal on the even transponders with the signal meter, but it will fail on setup. Any ideas? I called DTV and they are sending someone out to align dish again.
